Unauthorized Access Blocked (Access Process Data)

Hello: I checked the security history on my laptop the other day and saw the message in the heading above. The security history showed that these attacks are happening about once per minute or more. I then checked the two desktops on my home network and saw that security history was reporting the same issue on both of them. I rebooted the two desktops in safe mode, disconnected from the internet, and ran a full system scan with Norton 360 and Super Anti-Spyware. All I found were tracking cookies on Norton and I found adware.mywebsearch on Super Anti-Spyware. I deleted all the cookies with Norton 360 and quarantined adware with Anti-spyware. I then rebooted and connected to the Internet. After a few minutes I checked security history again and saw these attacks were continuing. The actor is c:\acer\empoweringtechnology\eperformance/memcheck.exe The target is c:\ProgramFiles\Norton360\Engine\4.3.0.5\ccsvchst.exe Is somebody trying to hack into my home network? What can I do to stop these attacks? Why is this happening? Thank you for any assistance you can offer me.

Re: Unauthorized Access Blocked (Access Process Data)

What you describe are Norton Product Tamper Protection events, which are normal and harmless. Legitimate programs often attempt to access Norton files and processes. All such efforts are blocked in order to prevent Norton's operations from being disrupted or compromised by any outside agent, legitimate or malicious. These are not attacks, and Norton is simply logging the events. The outside programs are only prevented from interfering with Norton, and are otherwise allowed to run normally. Threats to your computer that require your attention will be announced through Norton alerts on your PC. The Norton logs are simply a record of Norton's activities.

Thank you very much for your quick reply to my question. I have only noticed this recently in my security history and thought my computers were under attack. I am relieved that this is nothing to worry about.
